(b) From the fourth CB trigger, trading will resume after a 5-minute halt, but the CB trigger level will not be expanded (for the gold example above, the CB trigger level will stay at JPY 400). However, when deemed necessary by the Exchange, the halt period and trigger level expansion may be modified.

(2) Rubber

(a) For the first and second CB trigger, the trading session will be halted for 5 minutes from the time of the trigger.
Trading will then resume with an expanded CB.
* CB Trigger Level after First Trigger = 10 (initial trigger level) + 10 (expansion amount) = 20
* CB Trigger Level after Second Trigger = 20 (previous trigger level) + 10 (expansion amount) = 30

(b) From the third CB trigger, trading will resume after a 5-minute halt, but the CB trigger level will not be expanded (the CB trigger level will stay at JPY 30). However, when deemed necessary by the Exchange, the halt period and trigger level expansion may be modified.
